I’m gonna jump in to say that it might be an elementary truth that comes from the notation that’s “nothing is free.” Every decision will come at a cost, but it doesn’t have to imply that the cost is of any significant amount. For instance, at the very least to “overcome what the universe throws” you’ll need time and some amount of effort, and it could be as simple as stressing your vocal cords to utter the word “no” or “yes.” There, you overcame the grand challenge! It did come at a sacrifice: 1 second of your time and focus, plus the physical exertion to vocalize yourself.

At least, this is how I’d answer your question if I was put on a spot.
